Piston ring compressor tool system

Abstract

The piston ring compressor tool system comprises a compression skirt. The skirt has an interior surface and an exterior surface. It also has an upper edge and a lower edge. The tool system has a hollow, generally tapered, cylindrical tubular form and is further configured in a shape of an upper frustroconical funnel. The funnel forms a planar inlet within the interior of the upper edge. The funnel further forms a lower cylindrically shaped outlet within the interior of the lower edge. The outlet is parallel to the plane of the inlet and is for discharging the piston and ring assembly into a bore. The compression skirt has a generally outwardly curved upper horizontal portion. The lower horizontal portion is generally plumb to the plane of the opening of the lower edge. The middle horizontal area is a transition area between the radian outward curve of the upper horizontal portion and the generally plumb surface of the lower horizontal portion.

What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows:  
     
       1. A piston ring compressor tool system for safely and conveniently compressing piston rings for easy piston placement into a bore, comprising, in combination; 
       a compression skirt comprising an imperforate strip of flexible form-retaining material having an interior surface and an exterior surface and a peripheral edges formed there between including an upper edge and a lower edge and two side edges, the strip being rolled into a hollow generally tapered cylindrical tubular form having overlapping side edges thereby having an internal edge and an external edge, the overlapping configuration allowing for expansion and contraction of the overall radius of the compression skirt during operation and use, the strip being further configured at its upper extent in a shape of a generally outwardly flared upper frustroconical funnel at an angle of between about 10 and 15 degrees and including a continuous upper edge in an essentially circular configuration and with the funnel forming a planar inlet within the interior of the upper edge for receiving a piston and ring assembly and the strip further forming a planar cylindrically shaped outlet at its lower extent within the interior of the lower edge parallel to the plane of the inlet for discharging the piston and ring assembly into a bore of an engine, the compression skirt also having an upper horizontal portion and a middle horizontal portion and a lower horizontal portion, the compression skirt having a generally outwardly curved upper horizontal portion and having a lower horizontal portion and including a continuous lower edge in an essentially circular configuration which is generally plumb to the plane of the opening of the lower edge and having a middle horizontal area which is a transition area between the radial outward curve of the upper horizontal portion and the generally plumb surface of the lower horizontal portion whereby the interior surface decreases in diameter from the upper edge to the lower edge over at least the majority of the length of the skirt;  
       a compressing ring assembly comprised of a flat strip of rigid form-retaining material comprising a generally circular configuration having a compression strap and a compressor mechanism, the compression strap having an upper edge and a lower edge and two side edges and an internal surface and an external surface and an edge there between, the surface of the compression strap having a regular surface with parallel slots for receiving the traction from the compressor mechanism, the compressor mechanism, having a rotatable threaded coupler in the form of a bolt with threads for pulling on and shortening the circumference of the compression strap, the threads of the rotatable compressor mechanism being configured to mate to and be in contact with the compression strap thereby enabling the compressor mechanism to shorten and lengthen the overall circumference of the compression strap by rotatably shortening and lengthening the circumference of the skirt; and  
       an attachment weld coupling the compressing ring assembly to the outside middle horizontal portion of the compression skirt allowing the compressing ring assembly to shorten and lengthen the internal radius of the compression skirt by shortening and lengthening the circumference of the compressing ring assembly.  
     
     
       2. A piston ring compressor tool system, comprising: 
       an imperforate compression skirt having an interior surface and an exterior surface and an upper edge and a lower edge having a hollow generally tapered cylindrical tubular form being further configured in a shape of an upper frustroconical funnel with the funnel forming a continuous upper edge in an essentially circular configuration with planar inlet within the interior of the upper edge with the internal inlet and further forming a lower cylindrically shaped outlet with a continuous lower edge in an essentially circular configuration and with the outlet within the interior of the lower edge parallel to the plane of the inlet for discharging the piston and ring assembly into a bore, the compression skirt having a generally outwardly curved upper horizontal portion and having a lower horizontal portion which is generally plumb to the plane of the opening of the lower edge and having a middle horizontal area which is a transition area between the radian outward curve of the upper horizontal portion and the generally plumb surface of the lower horizontal portion whereby the interior surface decreases in diameter from the upper edge to the lower edge over at least the majority of the length of the skirt.  
     
     
       3. A piston ring compressor tool system as described in  claim 2  wherein the compression skirt comprises a strip of flexible form-retaining material, the strip being rolled into a hollow generally tapered cylindrical tubular form having overlapping side edges the overlapping configuration allowing for expansion and contraction of the overall radius of the compression skirt during operation and use. 
     
     
       4. A piston ring compressor tool system as described in  claim 2  wherein there is further provided a compressing ring assembly comprised of a flat strip of flexible form-retaining material in a generally circular configuration having a compression strap and a compressor mechanism, the surface of the compression strap having an regular surface with slots for receiving the compressor mechanism, the compressor mechanism having a rotatable bolt and threads for pulling on and shortening the circumference of the compression strap, the threads of the bolt being configured to mate to and be in contact with the slots of the compression strap. 
     
     
       5. A piston ring compressor tool system as described in  claim 2  wherein there is further provided an attachment element for coupling the compressing ring assembly at the point of the compressor compression skirt allowing the compressing ring assembly to shorten and lengthen the internal radius of the compression skirt by shortening and lengthening the circumference of the compressing ring assembly. 
     
     
       6. A piston ring compressor tool system as described in  claim 2  wherein there is further provided an attachment element for coupling the compressing ring assembly at the point of the compressor compression skirt allowing the compressing ring assembly to shorten and lengthen the internal radius of the compression skirt by shortening and lengthening the circumference of the compressing ring assembly.
